To aZZ whom it may concern: the section being taken on line 4 4 of Fig. 3, Be it known that I, JOSEPH A. GROEBLI, a and exhibits also the section-line3 3, on which resident of the city, county, and State of New the section of Fig. 3 is taken. Fig. 5 is a York, have invented certain new and useful broken-away side elevation of the cam and 5 5 5 Improvements in Embroidering-Machines, of sprocket-wheel, showing their intermediate which the following is a specification. connector.

Fig. 3 is an enlarged detail sectional 1 as of considerable length. This three-armed elevation of the stopping mechanism formlever K is shown clearly in perspective in ing part of the disconnecting mechanism, all Fig. 7. One of its depending arms it is proof which willbe clearly described hereinafter. vided with a sleeve 70, (see Figs. 4 and 7,) in 50 Fig. 4 is a sectional plan View of the parts which a stem 70 works. This stem k conshown in Fig. 3 and their adj unctive parts, nects with a crescent 70 carried by the lever K for entry into the cam-groove e of the cam O, and is slotted at 10 to receive a stud 10 on a jacquard-rod 76 This jacquard-rod is operated by the jacquard to enter or remove the crescent 70 from the cam at the proper times and to enter the stem of the crescent into a hole h or 10 to secure it in position to reenter the cam, so as to render the mechanism operative. The depending arm 70 of the three-armed lever K is in such position as to strike the trip 0 of the latch 0 when I the arm has been swung, as willbe explained. The arm 7s is shown as provided with an are it notched at 76 70 to receive a latch 70 which, entering either notch, serves to hold the threearnied lever stationary, so that the crescent will be properly positioned for entrance into the cam. The restoring mechanism for the latch c is shown as consisting of an arm I, projecting into the path of the latch c to restore the same, as will be explained.

Having got thus far, it will be profitable to explain the action of the parts heretofore described in order that the subsequent explanation of their interaction with the other parts may be fully understood. This operation is as follows: We will suppose the shaft 0 to be rotating and the latch to be in the position shown in Fig. 5, when it will couple the cam O and the sprocket-wheel D, so that from the said shaft O,cam,and sprocket-wheel the shaft F will be driven, thereby driving the embroidering-machine. W'Vhen it is desired to disconnect the embroidering-machine from its driving mechanism, the jacquard acts to reciprocate the rod k entering the crescent 70 into thecam-groove c of the cam O, and as the cam revolves the three-armed lever K will be swung to the left, bringing the arm 7.7 into position to strike the trip 0 of the latch to swing the same free of the pin cl on the cam C, so as to swing the latch on its pivot into such a position as to engage the notch c with the spring bolt or latch 0 thus holding the latch clear of the pin 61 and allowing the cam to run free from the sprocket-wheel, so that the shaft C will revolve the cam without producing any motion of the sprocket-wheel, and hence the ernbroidering-machine being deprived of its power will stop. This stopping, however, should be gradual and should be brought about in a certain and positive fashion, so that the parts will always stop in the same position ready for rengagement with the cam. This is effected in the present instance by suitable stopping mechanism, which will now be described. Secured to or made integral with the sprocket-wheel D is a gear J, which rotates with the said sprocketwheel. Working vertically in guides at on the brackets A of the frame A is a frame A composed of ways a a, joined by bars ct tand carrying a slide a which slide carries oppositely-placed racks a a.

gaged with the gear J. The frame A is freely movable vertically on the guides e and the These oppositely-- placed racks are adapted to be alternately en-.

slide a is freely movable laterally on the said frame, so that the rack may be raised and lowered by raising and lowering the frame and the slide may move laterally on the said frame, the said racks being, as aforesaid, rigidly secured to the slide a Mounted in proximity to the frame are shafts a a (see Figs. 3 and 8,) the shaft a carrying a cam a entered and working between the ways ct a of the frame A at one end thereof and the shafta, carryinga cam a likewise entered between and working in the ways a at the other end of the frame, Each of these cams is provided with an arm M, which arms are connected by a-yoke a carrying pins a and e The third arm 70 of the three-armed lever K is provided .at its lower end with a hub k -which carries a pin 70, provided with a loose block 70 (see Figs. 3 and 4,) which block enters a slot in the slide a so that when the three-armed lever is swung, as before described, the slide a and racks will move with it. One of these racks at a time meshes with the gear J, so that the rotation of the said gear is governed by the action of the earn 0 on the three-armed lever K, so that when disconnecting is being eifectedthe arm K, swinging slowly to the left under the action of the cam, will gradually decrease the speed of the gear J, and consequently gradually bring the embroidering-machine to rest. When the machine starts up again, it is necessary to disengage the upper rack from the gear and engage the lower rack therewith. As the gear always turns in the direction of the arrow in Fig. .3, it will be necessary to engage the lower rack a with the gear, so that as the arm K moves to the right under the action of the cam 0 it will impart motion to'the said gear J, so as to speed it up from a position of rest to a speed equal to that of the rotating cam C, so that when the head of the latch c strikes the arm I the cam C and sprocketwheel D will be running at the same rate of speed and there will be noshock when the connection is made. This shifting. of the rack is effected by turning the cams a" a on little shafts a a to raise the frame A carrying with it the slide a and racks a a This swinging of the cams a a is accomplished by swinging the yoke a by means of a threearmed fish-tail lever M, pivoted upon an extension 70 of the arm 7.2 This three-armed lever is shown as pivoted at the point and provided with armsm m and a fish-tail or wedge piece m which cooperates with either pin a or a to swing the yoke a to the right or to the left; The various positions of the lever I69 and the pivoted fish-tail piece M are shown in dotted lines in Fig. 8, the two extremities of the throw of said lever being clearly shown. As shown in full lines, the arm m of the fish-tail lever has just been actuated to swing the said fish-tail lever on its pivot to throw the fish-tail piece m to the right, thus carrying the yoke a with it and lowering the slide carrying the racks, so as to mesh the upper rack a with the gear J. YVhen in its opposite or dotted-line position, the arm 10 brings the fish-tail lever into contact with the pin a, and the cam L, rotating, acts upon the arm m of the fish-tail lever so as to swing the same on its pivot, causing the fish-tail piece on to push against the pin a to throw the yoke a to the left, thus raising the slide carrying the racks by the mechanism described to bring the lower rack into mesh with the gear. I will now proceed to describe a complete cycle of operations, so that the seriatimoperations just set forth may be understood.

Vv e will suppose the parts to be in the position shown in Fig. 2. The jacquard acts and enters the crescent 75 into the camgroove 0 of the cam C, which, rotating in the direction of the arrow in Fig. 2, causes the said crescent to traverse the said groove and to swing the three-armed lever K to the left at a progressivelydecreasing rate of speed. As the three-armed lever K swings it brings its arm 10 into a position where it will strike the trip 0 (see Figs. 4 and 5) of the latch 0 thus raising the said latch clear of the pin (1 and engaging the recess 0 of the latch, with the spring-bolt c holding the said latch clear of the pin (Z. The cam O and the sprocketwheel D have now been disconnected and the cam 0', being rigidly connected to the shaft 0, will revolve free of the said sprocket-wheel, which is loose on the shaft. At about the time the latch c is worked by the arm k the upper rack, which, as will be understood, is being moved to the left by the swinging arm is of the three-armed lever K, will mesh with the gear J, and as the rack moves progressively slower under the impulse and government of the progressivelyslower-movin g three-armed lever K the said gear, and consequently its connected embroidering-machine, will be brought gradually to rest. As the arm 7.2 is about to reach the left extremity of its swing or stroke the fish-tail piece m of the three-armed fish-tail lever M is thereby brought against the pin a 'and the cam L will come against the arm m of the threearmed fish-tail lever M and, swinging it upward, will cause the fish-tail piece to thrust the pin Ct EtDCl its connected yoke to the left, thereby swinging the said yoke into the position shown in dotted lines and causing the cams ((1 60 to raise the frame A, carrying with it the slide a to disengage the rack a from the gear J and to engage the rack a with the said gear, the parts having now come to rest. When the parts have been brought to rest, the crescent has reached about the pointo: in the cam-groove c, at which instant the jacquard again acts to withdraw the crescent from the cam and enter its stem into a hole to secure it in position.

The embroidering-machine being brought to a standstill, any desired manipulation of the fabric-frame maybe effected and actions performed on the fabric, if desired-for instance, bore-points may be operated to pierce the fabric while the embroidering-needles no longer operate.

It will be remembered that the three-armed lever K having been moved to the left the crescent or are it carried thereby, will have been moved sufiiciently far to the left to allow the latch k to drop into the notch 75, so that the said arm will be held at the left extremity of its swing by the latch entering the said notch k \Vhen the proper moment for reconnecting the embroidering-machine has arrived, the jacquard operates at such an instant of time as to enter the crescent 7.1 into the rotating cam at the point a; and to withdraw its stem 70 from the hole, and at the same time rocking the latch by any suitable means, such as the arm'h to release the arm from its locked position. Then as the cam revolves it will carry the three-ar1ned lever to the right. The first effect of this movement to the right is to start the wheel J through the medium of the rack a and as the speed of the arm K gradually increases the speed of the rack of, connected thereto, and wheel J, meshing therewith, will likewise gradually increase until in a few tenths of a second the wheel J is being driven at the same rate of speed as the cam C, at which instant the latch 0 carried by the sprocket-wheel D, which moves with the gear J, will be just passing under the arm I, which arm will force the said latch inward at the proper instant to engage the said latch a over the pin d on the cam, so that the sprocket-wheel D and the cam G are now again coupled. The last part of the movement of the arm K serves to bring the slide, 850. to rest and to bring the fish-tail lever into position (see Fig. 8) to be struck by the rotating cam L to throw the yoke a into the position shown in Fig. 3, where the racks will be completely disengaged from the rotating gear, but will be in such a position that the upper rack will engage the said gear when the lever 7c shall again begin to move to the left in obedience to the action of the jacquard. As soon as the yoke has been thrown, as just described, the jacquard operates to withdraw the crescent 70 from the cam O and enter the stem 70 in a hole to receive it, so that the embroidering-machine will proceed to do i ts work in the ordinary manner until at a predetermined time the jacquard again acts to set the disconnecting mechanism into operation.
